68.6 Binding the Client to the Service

For the purposes of this tutorial, the client is the MainActivity instance of the running application. As previously noted, in order to successfully bind to a service and receive the IBinder object returned by the service’s onBind() method, it is necessary to create a ServiceConnection subclass and implement onServiceConnected() and onServiceDisconnected() callback methods. Edit the MainActivity.kt file and modify it as follows:

package com.ebookfrenzy.localbound

 

import androidx.appcompat.app.AppCompatActivity

import android.os.Bundle

import android.content.ComponentName

import android.content.Context

import android.content.ServiceConnection

import android.os.IBinder

import android.content.Intent

 

class MainActivity : AppCompatActivity() {

 

    var myService: BoundService? = null

    var isBound = false
